Override default validation attribute

[ajcastro]

The default code for validation attribute is using Str::lcfirst($this->getLabel()) which is repeated on the following places:

• vendor\filament\actions\src\Imports\ImportColumn.php getValidationAttribute()
• vendor\filament\forms\src\Components\Concerns\CanBeValidated.php getValidationAttribute()
• vendor\filament\tables\src\Columns\Concerns\CanBeValidated.php getValidationAttribute()

I would like to override this behavior for example replacing the code with:

Str::lower($this->getLabel())

Idea:
Probably we can add a static $defaultValidationAttributeCallback on those three then register those callback on service provider.

use Filament\Actions\Imports\ImportColumn;
use Filament\Forms\Components\Concerns\CanBeValidated;
use Filament\Tables\Columns\Concerns\CanBeValidated as TableCanBeValidated;


ImportColumn::registerDefaultValidationAttribute(fn (ImportColumn $component) => Str::lower($component->getLabel()) );
CanBeValidated::registerDefaultValidationAttribute(fn ($component) => Str::lower($component->getLabel()) );
TableCanBeValidated::registerDefaultValidationAttribute(fn ($component) => Str::lower($component->getLabel()) );

if this were not registered in service provider, validation attribute will behave originally.

I found that the solution is this:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Str;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        //
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        \Filament\Forms\Components\Field::configureUsing(
            function (\Filament\Forms\Components\Field $component) {
                $component->label(
                    fn($component) => Str::title(str_replace('_', ' ', $component->getName()))
                );
                $component->validationAttribute(
                    fn($component) => Str::lower($component->getLabel())
                );
            }
        );

       \Filament\Tables\Columns\Column::configureUsing(
            function (\Filament\Tables\Columns\Column $column) {
                $column->label(
                    fn($column) => Str::title(str_replace('_', ' ', $column->getName()))
                );

                if (method_exists($column, 'validationAttribute')) {
                    $column->validationAttribute(
                        fn($column) => Str::lower($column->getLabel())
                    );
                }
            }
        );


        \Filament\Actions\Imports\ImportColumn::configureUsing(
            function (\Filament\Actions\Imports\ImportColumn $component) {
                $component->label(
                    fn($component) => Str::title(str_replace('_', ' ', $component->getName()))
                );
                $component->validationAttribute(
                    fn($component) => Str::lower($component->getLabel())
                );
            }
        );
    }
}
